Appendix E. Model statistics for the general linear models with Poisson error term for species richness divided into different groups based on taxonomy and frequency of sexual reproduction.

TABLE E1. Model statistics for the GLMs with poison error term for species richness divided into different
groups based on taxonomy and frequency of sexual reproduction. Z-values and P values are given for the contribution of distance to mature forest edge in a model with site identity as a factor and the co-variables (if significantly contributing): frequency of boulders (BOUL), meter of small logs (LOGS), meter of large logs (LOGL), and frequency of dry ground (DRY). Dependent variables were the number of species recorded at different distances from the mature forest edge. N = 23.
